Very nice presentation by Frank Griesshammer on the subject of the Hershey Fonts: https://vimeo.com/153653610 He does a superb job explaining how a font invented in 1967 by a mathematical physicist at a US Weapons Lab became essential for the last 40 years of technical writing. And is also an interesting font for actual font designers today :-) Tim N3QE [https://www.bing.com/th?id=OVP.0QZVssVrJ4Ynm3h5opaOeAEsCo&pid=Api]<https://vimeo.com/153653610> Frank Grie?hammer ?

Toshiba Laptop needing new home

by mtapley＠swri.edu

All, in San Antonio (Texas), I have a Toshiba Satellite 2065CDS/4.3 laptop, Model number PRS206U-A, whose owner wants to give or throw it away (preferred give). It has a 16-bit ethernet card including dongle and driver floppy, annoying eraser-head cursor control with replacement eraser heads, USB port, 3.5? floppy, CD drive. Starts up to Toshiba screen and shows 160 MBytes of RAM. I watched it boot to Win98 once and fail to boot many times. I think the owner had it dual-booting to Linux as well, but he is having the disk wiped to make sure no personal information goes with it. The battery kept it running for only about 15 seconds on power-disconnect after being plugged in (running) for an hour or two, so probably not much battery life available. I think the freshly-cleaned hard drive has ~ 4 GB of space, don?t know for sure about that. Let me know if you are interested; I?ll forward inquiries to the owner as I get them. - Mark 210-522-6025 office 210-379-4635 cell

5.25- inch alignment disk needed

by spacewar＠gmail.com

I find myself in need of a 5.25-inch alignment disk. A few years ago someone mentioned a source for those, but I can't seem to find it. Is there still a source, or does anyone have one they'd be willing to sell? I could use an 8-inch alignment disk also, but don't need that as urgently.

P112

by bill.gunshannon＠hotmail.com

It's not really Classic Hardware, but it does run some pretty classic OSes.? Anybody here working with the P112?? I have had a couple for ages but never had time to play with them.? I see them now as a possible way to manipulate floppies (including 8") from classic systems so I decided to give it a try.? Problem is, it won't boot anything.? Not the disk that came with it and none of the images I got off the web. Anybody here know anything about them? bill

SGI SN-921 dial box working! (was Re: Seeking software for SGI/Sun dial box)

I got the script working and two things were impediments: 1) One of the SN-921 pinouts running around on the 'net is incorrect, as I posted. The *correct* place for the ground is DE-9 pin 7. I was apparently getting enough of a parasitic ground to get chars *from* the SN-921 but not *into* the SN-921. As it turns out, it appears the SN-921 as set up for the SGI is mute except for a single status success byte 0x20. If you send it an INIT command (also 0x20), it will respond with its success after a fraction of a second, which leads to another problem... 2) The python script dialbox.py slams the init code and a command to set the dials to auto-report all at once, before the SN-921 has a chance to initialize. So to fix that, I added a few extra lines to send the 0x20 INIT command, pause, check for a 0x20 response (INIT GOOD) _then_ send the AUTO command (0x50 0x00 0xFF), which sets all 8 dials (one bit per dial) to send back a 3-byte packet when twisted. With the custom serial cable fixed and the init sequence fixed in the Python script, I'm now getting the right data stream when I twist any of the knobs. I did get a copy of dialbox.c from http://www.geocities.ws/joekrahn/dialbox.tgz Jim Stephens tracked down that there was a massive GeoCities scan done in 2009 and the file I was looking for happened to be scooped up then. There are a number of dial box and button box command sets in that code which reveals some of the more complex behavior possible. Here's a slice of the command byte definitions... #define DIAL_INITIALIZE 0x20 #define DIAL_SET_AUTO_DIALS 0x50 #define DIAL_SET_AUTO_DELTA_DIALS 0x51 #define DIAL_SET_FILTER 0x53 #define DIAL_SET_TEXT 0x61 #define DIAL_SET_BUTTONS_MOM_TYPE 0x71 #define DIAL_SET_AUTO_MOM_BUTTONS 0x73 #define DIAL_SET_LEDS 0x75 #define DIAL_SET_ALL_LEDS 0x4b It should be possible to write up a protocol definition from studying the code. I do not have one of these button boxes so I can't validate its behavior. -ethan

The Famous Computer Cafe

by dmonnens＠gmail.com

Hello, I am trying to find anyone who has recordings of a radio program >from 1982-1986 called The Famous Computer Cafe. This was broadcast on KIEV in Glendale, KFOX in Redondo Beach, and NPR through Santa Monica College (here in 1984-1985). The program contained numerous interviews with all the movers and shakers of computers and software during that period, including Bill Gates, Steve Jobs, and Jack Tramiel. As such, this show is of high historical importance. There was somewhere between 100 and 200 episodes all told. I understand it was an extremely popular program among hobbyists at the time, so was hoping someone from the list might have recordings. If you have any recordings or know someone who might, please let me know! I have contacted the show's hosts, but we have only been able to locate a handful of recordings. Thank you! -- Devin Monnens www.deserthat.com The sleep of Reason produces monsters.
